Yep, same here. The only contact I'd get would be on working days and that too strictly related to work stuff. If it's a long weekend, it's guaranteed that no one would contact me for the entire period. It's always been that way too. I remember once I went so many days without any kind of human contact, that I began to ask myself if I even actually exist anymore, and I wanted to walk in traffic just to confirm if cars see me and stop for me.
Like, what do you even have to do to get people to care about you and get attached to you? I've tried talking to people, joked and laughed with them, cared and did things for them but after all that, just... nothing. Once I move out of their immediate presence, I basically disappear to them. It's really strange. It feels like I'm some kind of alien watching human society from a distance.
